unfortunately jpod101's weak side is kanji studying (in my opinion at least).
I am using the jpdos101 kanji bank as a reference tool and do the learning process offline with old fashioned hand written flash cards and repetition.
As a reference for stroke order sample sentences and such i use a few different resources like [url]wadoku.de[/url] and http://lingweb.eva.mpg.de/kanji/
(those two are german sites but there are english ones you could use) and books like Kodansha Kanji
Find a listing of jplt n4 kanjis here for example http://nihongoichiban.com/2011/05/22/complete-list-of-kanji-for-the-jlpt-n4/
It would be great if jpod101 could expand on kanji learning, cause right now its of little to no use what you get on this site regarding kanji.
Besides that everyhing else here (Lessons and stuff) is great.
